Analysis

The ag pilot was completing his last spray pass when the engine began to run roughly. He pulled up to shut off the spray pump, and the engine subsequently quit. He attempted to force land the airplane on a dirt farm road, however upon touchdown he was unable to maintain directional control on the rough surface. The airplane collided with a ditch, and was substantially damaged. An FAA inspector visited the crash site and examined the wreckage. The aircraft had an adequate amount of fuel on board, and no evidence of a mechanical failure or malfunction could be found. The engine was started and successfully ran after the accident. The reason for the engine power loss could not be determined.
